A li ati fil d December 6, 1904- Serial No. 235.692-

.To all whom it may concern:

Be it known that I, HENRY DIECKS, a citizen of the United States, residing at Eastport, in the county of \Vashington and State of Maine, have'invented a new and useful Can-seaming Machine, of which the following is a specification. v.

This invention relates to mechanism employed for the seaming of cans, and has for its principal object to provide a novel mechanism for quickly and eflectively seaming tin cans without the employment of solder and with or without the employment of an adhesive cement. v

A further object of the invention is to provide a double seaming-machine in which provision is made for preventing the wear that usually takes place as a result of sliding friction on the members which carry the rollerdies, such parts Wearing away rapidly in the machines in ordinary use and requiring constant adjustment and frequent renewal of the arts. p A still further object of the invention is to provide a novel form of seaming-machine which to some extent is automatic in its nature, the seaming operation and movement of the parts automatically stopping at a predetermined time and the seamed can being removed from engagement with the seaming devices. v v

With these and other objects in view, as

will more fully hereinafter appear, the invention consists in certain novel features of construction and arran ement of parts hereinafter fully describe illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details ofthe structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figurel is a side elevation of a can-seaming machine constructed in accordance with the invention. Fig. 2 is a plan view of the same. Fig. 3 is a detail sectional view through the chuck .and illustrating the positions of the die-actuating cams, the view being taken on the line 3 3 of- Fig. 2. Fig. 4 is an inverted plan view illustrating the construction of the roller-die carriers and their supporting devices. Fig. 5 is a detail perspective view of the cam for controlling movement of the forming-die. Fig. 6 is a sectional elevation of a portionof the plan view, and Fig. 8 an elevation, of one of the can1-c ntrolled levers. Fig. '9 is a plan View, and Fig.1() is an elevation, of one of the roller-die-carrying members. Fig. 11 is a side elevation of thelower die. similar view of the seam-flattening die;

Similar numerals of reference are employed to indicate correspondim parts throughout the several figures of the rawings.

The working parts of the machine are supported on asuitable, frame including a base 10, a standard 11, and a horizontally-disposed arm 12. The standard is provided with, a bracket13, in which are formed bearings for the reception of a horizontally-disposed shaft 13, having fast and loose pulleys 14 and a bevel-gear 15, the latter intermeshing with a bevel-gear 16 on a shaft 17, that extends vertically through the standard and is provided at its upper end with a worm 18 and at a point inter-mediate of its length with a pinion 19, the latter projecting through suitable openings formed in the front and rear walls of thestandard.

Secured rigidly to the outer portion of the arm 12 is a stationary shaft, 21, on which is mounted a revoluble disk 22, the latter being supported by an annular flange 23 projecting outward from the lower end of the shaft 21.

19 and receives movement therefrom.

On the lower end of the shaft 21 is a noncircular socket 25, receiving a correspondingly-shaped shank 26, that projects upward from a chuck 27, the chuck being stationary and held from downward movement by apin 29, fitting within a slot 30 in thelower end of the shaft, and undernormal conditions there is sufficient space between the top of the purpose hereinafter described.

31 of a contour corresponding to that of the cans to be operated upon, and the inner wall of said groove forms the boundary of a depending integral block 32, that fits within a recess formed in the top of the can, this block constituting a stationary anvil for supporting the can during the seaming operation.

of perforated bosses 34, through which extend per faces of levers36 and constitutingthe The chuck is provided with a cam-groove The revoluble disk is provided with a pair perforated bosses 3.5, projecting from the upmachine on the line 6 6 of F 2. ,Fig. 7 is a I The periphery of this disk is toothedto form I a gear 24, that intermeshes with the pinionv chuck and the wall of the recessed disk to permit upward IHOVQIDQHt of said chuck for a v axis oflswinging.movement of said levers.

The upper-ends of the bosses 35 are threaded for the reception of suitable nuts 37, by which the levers are retained in place. From the lower face of each lever depends a block 38, having a verticallydisposed groove 39, that forms practically a'continuation of the opening of the boss, but is of. angular form in cross-section, whilethe upper portion of the .10 opening in-the boss-ispreferably circular, although this is not essential. 'Each of the levers 36 is approximately crescentic in form and carries at its inner end an antifriction roller 40 that fits into the cam-groove 31, the

shape'ofthe latter dictating the course of .movenient of the .antifriction-roller, and, as

' previously 1 described, the chuck may be "moved vertically, so that, if desired, the rollers may --be. disengaged fromithe cam-groove zd-for'pur oses of renewal or repair.

On t e shaft 21 at a point above the disk 3 is. arranged a revoluble'sleeve or collar 42, having an annular groove 43 and provided with a pair of lugs 44, thesebeing connected 25 by vertical rods45 to a cross-bar 46, that isarranged somewhat above the top of the arm .12. The rods 45 extend :through guidingopenings in lugs 47, projecting from the arm 12,-and between the upper faces of these lugs and the cross-bar'46 are arranged compression-springs 48, that-tend-normally to hold the sleeve or collar in an elevated position.

Fitting inthegroove 43. of sleeve 42 is a collar 50, from which project two diametric- 3 5 ally-opposed arms 51. The outer ends of these arms are provided with bosses having openings for the-passage of the upper .ends of .cam-rods,52,:and-these rods are threaded for the rece tion of suitable locking-nuts 53, by which t eymay-be first adjusted and then firmlylocked in position. The cam-rods pass downward through the openings in the bosses 35 and at their lower ends are provided with cams 54, that are of angular form in sec 4 5 tional plan and fit within the correspondinglyshaped recesses 39 in the pendent bosses 38.

At a point intermediate the ends of each 1ever 36 is pivoted a die-carrying lever 56. These levers are approximately crescentic in form, and the inner-end ofeachis provided with a roller-die, one being a seam-forming die '57 and the other a flattening-die 58, as is well understood in this art. The opposite or outer end ofeach lever 56 is-reduced in 5 5' width and is provided with a threaded opening 59-.for the passage of a screw 60, the latter beingarranged for engagement by the inclined face'ofthe cam 54, and when so engaged the roller-dies carried by said levers 60 are renderedoperative. When not engaged, the roller-dies are free to swing to a limited extentand will not operate on the cans.

In suitable bearings 61 at'the top of the frame is arranged a'horizontally-disposed 65 shaft 62,-having atone end a'Worm-wheel 'ried by a rock-shaft 67.

has a projecting pin or roller 65, which may be engaged by a clutch-operating arm 66, car- The rock-shaft is mounted in a bearing formed in a projection 68, projecting from the frame, and at that end opposite the clutch-operating arm is provided with a rocker-arm 69. The opposite end of the arm 69 is connected by a rod 70 to the-inner end .of a manually-operable lever 71, pivoted on a pin 72, that is carried by a bracket 73, projecting from the frame. At a point intermediate the ends of the rockerarm 69 is'an antifriction-roller 74, which may enter a recess 75, formed in a disk 76, that is keyed or otherwise secured to the horizontal shaft 62, and when said roller enters the re cess the arm 66 will'descend, and its beveled end portion will engage with the pin or roller 65 and move the latter outward until the clutching member 64 is disengaged from the worm-wheel, so that the latter may rotate freely on the shaft without effecting movement of said shaft.

At the'forward end of the shaft 62 is a cam 79, adapted to engage a pin or antifrictionroller 80,- projecting from the cross-bar 46,

and when this cam turns the bar and the rods '45 will be forced downward, and the movement will be transmitted to the two camrods 52, thus setting the roller-dies into operation.

The bracket 73, hereinbefore referred to, forms, in connection with a second bracket 82, bearings for the reception of a verticallydisposed spindle 83, that is provided at its upper end with a table 84 of a contour correspondin to that of the can to be seamed and on whic the can isplaced and then moved u ward for engagement by the seaming-dies.

ear the lower portion of the spindle 83 is secured a collar 85, connected to the lever 71 by a twoart link 87, and the two members of the lin being separated by a yieldable cushion 88, so that slight independent play of the parts will be permitted. The rear end of the operating-lever 71 is connected to the rod 70, and on said rod 70 is, a collar 88, between which and the lug 89, projecting from the frame, is arranged a helical compressionspring 90, that tends normally to depress the rod and kee the roller 74 in contact with the periphery o the recessed disk 76.

In the operation of the device a can to be seamed is placed on the table 84 and the lat.- ter is moved upward by de ressing the handled end of the operatingever 71, so that IIS the recess 75,s that the constantly-rotating worm 18 transmits movement through the worm-wheel 63't0 the shaft 62. time the constantly-rotating pinion 19 is slowly revolving the disk 22. The can being now in correct position and the roller-die bearing loosely against its edges, the turning of the cam 79 forces the two cam-rods 52 down. The cams at the lower ends of the .rods 52 are arranged at different levels, the

cam which forces the forming-die tooperative position being of the character shown In Fig. v and operating in advance of'the'cam employed for forcing the flattening -die into I o erative position. It will be observed that a ter the cam-face of the rod 52 (shown in Fig. 5) has passed beyond the set-screw may enter a recess 54, formed in the -camface,and thus permit the forming-die to move from active engagement with the seam during the time the opposite cam is moving operative position. In order to provide for more accurate movement and prevent excessive play, the two levers 56 are connected to the bosses 38 by means of light tension-springs 81 On downward movement of the cam-rods 52 the cam of the forming-die will first'move to operative position,

a and the forming-die will thereuponmove into en wil be gradually forced thereagainst, this operation resulting in the formation of a seam. As the operation progresses the cam 79 will still furtherdepress the bar 46, and the camrods 52 and the second cam 54 will be forced to operative'position, causin the lever 56, that carries the flat pressing-die 58, to come into operative engagement with the formed seam, fiattenin the same. When the can has been raise; and the roller 74 has .been moved from its recess'75, the lease the handle,.and the roller 74 then rides on'the peri hery of the disk 76 until the shaft 62 has ma e one complete revolution, this resulting in the seaming of the can. Thespring 90 then comes into play as the recess 75 again approaches'a position under the roller 74, and the latter is helddown into the recess. This member results in moving the clutch-operating arm 66 to a position to engage the pin 65, and the members of the clutch are separated. Operative movement of the shaft 62' .then ceases, and atthe same time downward movement of the rod'70 causes the corresponding movement of the lever'71 and table'84, so

that the seamed can may be readily removed from position.

On reference to Fig. 4 it will be seen that the under. surface ofthegear-wheel' 24'is provided with two slots 82, arranged on curved lines struck from the centers of swinging movement of the levers 36. This permits the raising of the centrally-dis osed cam-disk 27 until the rollers 40 are whol free from the cam-groove, nuts 53 being first loosened, af-

'ward', At the same set-screw 60 said second lever, an adjustable screw agement with the edge of the can and operator willreable through the and ah anvil, a

ter which the ?levers 36 may be swungjout the vantifriction rollers 40' traveling through the slots 82 until they are clear of the periphery of thegear. This permits of any necessary adjustment .or renewalv of the arts. p Having thus describedthe invention, what is clainiedis 1.
